He uploaded his first video in 2009 — a video compiled of 300 straight selfies — and then began uploading videos every year.

But this year was an extra special milestone for him. It was his wedding day.

So Cornellier decided to mark the occasion accordingly, pulling together every single daily selfie from the past eight years.

The now-viral video, which has been viewed millions of times, shows the young man's transformation from a young bare-faced 12-year-old to a handsome groom on his wedding day last month — in under three minutes.

Last year, Cornellier revealed on Reddit his ultimate goal was to "have a record of my life to be able to look back on when I'm old".

"It'll be crazy to be able to show my kids this video," he added.

He also plans to carry on doing this for a very long time.

"I plan on continuing until I am physically unable to continue. I don't see any reason why I would ever stop.

"Seeing my whole life flash in front of my eyes will be so fascinating once I'm older."
